1. Geometric discretization for incompressible magnetohydrodynamics on the sphere
Sammanfattning : Many physical processes are modelled by partial differential equations (PDE), and their efficient discretization is still a challenging problem and an actively developing field. An important class of models arising in mathematical physics represents PDEs formulated in terms of a Lie-Poisson structure on the dual of infinite-dimensional Lie algebras, such as the Lie algebra of vector fields.

2. Symplectic methods for isospectral flows and 2D ideal hydrodynamics
Sammanfattning : The numerical solution of non-canonical Hamiltonian systems is an active and still growing field of research. At the present time, the biggest challenges concern the realization of structure preserving algorithms for differential equations on infinite dimensional manifolds. LÄS MER
3. Geometric Discretization in Shape analysis
Sammanfattning : Discretizations in shape analysis is the main theme of this licentiate thesis, which comprises two papers. The first paper considers the problem of finding a parameterized time-dependent vector field that warps an initial set of points to a target set of points. LÄS MER
